What size spacers to run on a F83 on H&Rs

[Asesino_m4]

I lowered my F83 on H&R springs and want to see what's the right size spacers to put on the car without rubbing.

In addition my man ^ would like to know if the 400 pounds difference from a coupe affect the max size spacers he's able to run or no?

F83 is the same as other F8x. 15mm front and 12mm rear look the best.

@JNoSol so he'd be able to do 18mm rear no rub then
